12 I. IJIMA : HEXACTINELLIDA. I. 



As in the case of the lines that center at Togeyama, so also 

 in the present series the fishermen are wont to distingnish by 

 name a greater number of lines than I have given. For instance, 

 they speak of ' 3Iera handai-kobu,^ by which is meant the positions 

 whence as much of the Mera headland as in shape resembles the 

 hump-like protuberance (Jap.: hohu) on the snout of a Labrid 

 fish, Chœrops japonicus (Jap.: Kandai), is seen to project beyond 

 Sunosaki ; of ' 3Iera Y-j,' when only one half of the first hill of 

 Mera is visible in a similar way ; of ' 3Iera lYo,' * liera 2Y2/ 

 etc. 



deferring to the blue lines on PI. XIV, it will now be clear 

 what points on the Siigami Sea are meant by such expressions 

 as, ^Koto-line and Mera just out,^ ^ Kozuha-line by 3Iera 1,' 

 ' Yahagi-line by Blochiyama,^ ' Outside Okinosê ' by Iwado-line,' 

 &c. 



There still remain to be mentioned a few more names of 

 localities where the Misaki fishermen do most of their deep-sea 

 fishing (chiefly for Bathythrissa dorsalis) and which have yielded 

 us rich supplies of zoological specimens. 



By the name of Yodomi (meaning ' the stagnant water ') 

 is known the region of 400-500 fathom-lines, 11-18 kilometers 

 westward of Misaki. It is divided into Nishi-no- Yodomi, Naka- 

 no-Yodomi and Maye-no-Yodomi. 



Nishi-no- Yodomi, or the * Western Yodomi,' is on the 

 Koto-line, the other bearings being Tomisan -o Moroiso and 

 Enoshima NNE. 



Naha-no- Yodomi, or the 'Middle Yodomi,' lies on the 

 Kôzuha-line by nearly 3 fer a Yi-' 



3Iaye-no-Yodoiiii or the 'Front Yodomi,' so called on ac- 

 count of its being the nearest Yodomi to Misaki, is situated on
